Overview Of JC Jaw Crusher
European type industrial jaw crushers(Sales code: JC Series jaw crushers) undoubtedly becomes the most welcome crusher machine in the world without controversy. The European type industrial jaw crushers adopts the most advanced international crushing technology as well as the top-ranking skills in manufacturing industries. If you want to crush the hard and abrasion proof stuff materials with high efficiency, the European type industrial jaw crushers are your best choice in the world.

The Application Of JC Jaw Crusher
This series of jaw crusher is mainly used to crush mid hardness ores and rocks in metallurgical industry, mining, chemistry, cement making industry, construction, refractory, pottery and porcelain making for secondary and fine crushing. It is preferred to crush ores, rocks, slogs, feldspar, ballast, dolomite, manganese, talc etc, whose compressive strength is under 280Mpa. Maximum size of feed materials must be less than what is required according to the specifications.

The Features & Benefit Of JC Jaw Crusher
World-level manufacturing technology is adopted, perfect raw material is selected.
More advanced movable jaw assembly lengthens life of JC. Movable jaw assembly, composed of cast steel structure with high-quality, is driven by two big flying wheels which are also made from cast steel. Moreover, heavy eccentric axle is processed by forged mold. All of these make the JC series crusher extremely reliable.
Integral cast steel structure is adopted for bearing seat. Integral cast steel bearing matches well with the crusher frame, at the same time, radial strength of the bearing seat is highly strengthened. However, the separate bearing seat does not have this advantage.
Finite element analysis technology is adopted to make the crusher more stronger.
Crusher chamber adopts "V" structure which could make actual feed width comply with the nominal one.
Adjustment of the discharge part is more convenient.Discharge part of JC series crusher is installed wedge block, which makes discharge much simpler, safer and faster than the spacer on old style crusher.
Bearing with larger specification and stronger capacity are used.
A newly designed tooth-shape jaw plate, makes the available area of jaw plate longer, and enhances the capacity.

Main Parts Of JC Jaw Crusher
The JC series of jaw crushers in European style are mainly consist of frame, the rotation part of the eccentric bearing, the working part of the crushing cavity, the safety unit and the adjustment devices of the discharging opening.

Working Principle Of JC Jaw Crusher
The motor of JC Jaw crusher drives belt and belt wheel, when movable jaw plate is driven towards fixed jaw plate, material in the jc Jaw crusher machine is crushed or ground. Motor drives the movable jaw up and down through eccentric shaft. The angle between toggle plate and movable jaw increases when movable jaw moves up. The stones are crushed in this process. The angle between toggle plate and movable jaw decreases when movable jaw moves down, the movable jaw move away from fixed jaw by the pulling of rode and spring, the stuff crushed will be discharged from the output opening. This process will repeat. The moving jaw will crush and discharge the stuff circularly.
